通过洗涤和不洗涤两种方式对破碎C40废弃混凝土所得的再生骨料进行处理,采用两种不同搅拌、投料方式,加压成型制出抗压强度为15.62 MPa、透水系数为10.7 mm/s的透水混凝土,得出试验前经过洗涤的集料并采用水泥裹石的方式配制的混凝土明显优于其他方式配制的混凝土。

The recycled aggregate fi-om the waste concrete which the compressive strength is C40 is washed or not,by mixing and feeding,and press the samples to form the permeable concrete with a compressive strength of 15.62MPa and permeability coefficient of 10.Tmm/s.The conclusion is that the concrete which the aggregate was washed before trial and wrapped with cement is supe...
